Emerging infections provide clues about how pathogens might evolve when farm animals are protected from infection.

Tracking the myxoma virus in the wild rabbit populations of Australia has yielded insight into how pathogens and their hosts evolve.

The turtle-headed sea snake is losing its stripes, and researchers suggest that the change reflects adaptation to fouled oceans.

Their waters served as refuges during ice ages, allowing for adaptation and the emergence of new species.

Parallel evolution in jaws and teeth helped early mammals diversify their diets.

Harvesting lab-raised zebrafish based on their size led to differences in the activity of more than 4,000 genes, as well as changes in allele frequencies of those genes, in the fish that remained.

From fish harvests to cottonwood forests, organisms display evidence that species change can occur on timescales that can influence ecological processes.

The results of a historical primate behavior analysis suggest that species with fruit-filled diets evolved larger brains.

An analysis of 74 dinosaur species leads a group of researchers to reorganize the extinct animals’ evolutionary history.

Researchers are using multiple methods to study the origins of humans’ capacity to process and produce music, and there’s no shortage of debate about the results.

Anole lizards inhabiting the Caribbean islands display some of the key principles of evolution.

The small lizards adapted to unique niches among dozens of isles.

The Asian honeybee should have been crippled by low genetic diversity, but thanks to natural selection it thrived.

Report finds that pathologist involved in anonymous defamation case committed multiple acts of misconduct; growing eggs from stem cells; neutrophils’ role in metastasis; convergent evolution in birds

The unicellular ancestor of animals may have harbored some of the molecular tools that its many-celled descendants use to coordinate and direct cell differentiation and function, scientists show.

Researchers apply in vitro evolution to generate an RNA enzyme capable of copying and amplifying RNA.

Some thoughts on going to the Galápagos

Why does cooperation evolve most often in monogamous animals?

The modern human brain evolved in social and environmental settings very unlike today’s. Despite our cultural and technological progress, tribal instincts remain.
